IMPROVEMENT IN BED-BOTTOMS.

Specification forming part of Letters Patent No. 140,492, dated July 1,1873 application filed p May 17, 1873.

To all whom it may concern:

Beit known that I, DAVID FEANKEODER, of Wakarusa, in the county ofElkhart and State of Indiana, have invented a new and useful Improvementin Bed-Bottoms; and I do declare that the following is a true andaccurate description thereof, reference being had to the accompanyingdrawings and to the letters of reference marked thereon and being a partof this specification, in which- Figure 1 is a perspective view of myimproved bed with the invalid-bolster raised. Fig. 2 is a sectional sideelevation of the saine with the bolster lowered.

Like letters refer to like parts in both iigures.

The nature of this invention relates to an improvement in theconstruction of that class of spring-Slat bed-bottoms which are providedwith an adjustable bolster at the head, and is more especially designedas an improvement on the bed-bottom for which Letters Patent were issuedto this applicant and George W. McGeorge, on November 19, 1872, andnumbered 133,090. The invention consists, first,

in the peculiar method of supporting the slats in a transverse barsuspended in the bales of the springs; second, in the peculiar method ofsupporting and suspending the adjustable bolster, and in the generalarrangement of the various parts, as more fully hereinafter set forth.

In the drawing, A represents the frame of my improved bed-bottom, in thehead and foot pieces of which are inserted the ends of the doublehelical springs B B, Src., through the spirals of which a cylindricalrod, a, is in serted. The bales of these springs point upward andinward, and their ends are bent into loops, through all of which isinserted aNo. 9 wire rod, C, having bent in it a series of eyes, b, eachof which receives the rounded end of a slot, D, which is thus supportedat each end. In the bed-bottom, described in the above-mentioned LettersPatent, the tenons of the slats are received in eyes formed in the balesof the springs. In practice it is found that when the spring-bales weredepressed by pressure upon the slats, the eyes, being rigid with thebale, would incline with the depression of the bale and bind the tenonof the slat, preventing its free movement in the eye, and causing it tobend the bale. By supporting the slats in the manner shown, theseobjections are entirely obviated. At the foot of the frame a foot-slat,D, is supported across the ends of, but beyond, the slats D, by means ofC-springs c to support the lower end of the mattress. E is the lower,and E1 the upper bar of a bolster-frame, connected by slats E2,intermediately placed between the slats D, the bar E being suspendedacross and underneath the slats D by links d d, from a No. 9 spring-wirerod, e, laid across the slats, its ends being hooked under the edges ofthe outside slats. The barE is kept from moving out of place byradius-rods f f, connecting it with the springrod a at the head of theframe. The slats E, when the bolster is lowered to the horizontal plane,rest upon the rod U at the head ofthe main slats. Fis a bolster-prop,composed of three bars, forming three sides of a rectangle. The freeends of the side bars of this prop are hinged to the side bars of themain frame, and under cach is hinged a pawl', F', whose foot engageswith a ratchet on the head-part of the side bar. The pawls F areconnected by a rod, g, to compel them to move 1n unison.

The arrangement of the devices for adjusting the position and supportingthe bolsterframe are such that the latter is easily and readily fixed atany desired angle.

7h-at I claim as my invention, and desire to secure by Letters Patent,is-

1. r1`he arrangement of the rod C, provided with eyes b, with relationto the springs B for supporting the slats D, as shown and setforth.

2. rIhe combination, with the frame A, springs B, rods C, and slats D,ot' the bolster'- frame E El E2, links d, rod e, radius-rodsff,bolster-prop F, pawls F', and rod g, substantially as and for thepurpose set forth.

DAVID FRANKFODER.
